DELIVERY MEANS FOR SHEET-METAL PRESSES.

Specification of Letters latent. Patented'uly 29 1919 Application filed October 8, 1917. Serial No.'19 5 ,261,

To all whom it may concern:

Be it known that I, GEORGE WVILLIAM BERRY, a subject of the King of Great Britain, residing in Rose Bay, near Sydney, in the State of New South Wales, Commonwealth of Australia, engineer, have invented new and useful Improvements in Delivery Means for Sheet-Metal Presses, of which the following is a specification.

This invention relates to improvements in and connected with sheet metal presses for forming hinge members on and hingedly connecting the lids and bodies of sheet metal receptacles and it has been devised particularly-in order to provide delivery means for sheet metal presses whereby connected lids and bodies can be correctly closed and discharged from the press.

The invention is directed to that class of press which forms the subject-matter of my co-pending application for United States Letters Patent Serial No. 148,767 filed 15th February, 1917 and wherein three sets of dies areemployed for simultaneously treating receptacle bodies and lids, means being furnished for progressively and intermittently passing lid and body blanks. from one set of dies to another to form hinge members and connect the lids and bodies in three successive operations.

The prior invention referred to comprises a cast metal frame wherein is mounted a base carrying three removablebottom dies and a reciprocatingly mounted die head carrying a correspondlng number of top dies The top dies are adapted to move to and from and register with the bottom dies.

The lid and body blanks to be hingedly connected are fed to the machine through chutes placed at one side thereof and are directed to the bo-ttom dies along guideways by the intermittent operation of push rods reciprocatingly mounted in the top of the base. l/Vhen a lid-and body have been advanced toa position opposite the first bottom die they are thrust over the back and front, respectively, thereof by push pads that are carried on bars reciprocatingly.mounted on the base. The top dies are timed to operate when the lids andbodies have been thrust Y correctly on to the bottom dies, topartially form the hinge members.

When the lid and body are raised clear of the forming members of the bottom die they are moved outwardly by curved ejector arms anal placed in advance of fingers on the push ro s..

When a lid andbody have been removed from the first bottom die they are carried.

along the guideways to the second bottom die by the next inward stroke of the push rods. The lid and body are thrust onto the second bottom die by push pads operating in front and rear thereof and the operation of the second se-t of dies completes the f0rmation of the hinge members. p j

\Vhen the top dies commence to rise after completing the formation of the hinge mem bers the body and lid are moved outwardlyfrom. the second bottom die into the guide- Ways by ejector arms. a j

The body and lid shaped by the second die are then moved opposit the front and back respectively of the third bottom die by the next inward stroke of the push rods.

. The body is thrust on to the front ofthe thirdjbottom die by a push pad arranged;

and operating as before described. As the lid is carried forward opposite the rear of thethird die, it is. placed in a holder which is adapted 'to carry it forward and place the pintles thereon correctly beneath the bulbed tongues on the back of the body.

When the third top die descends it closes the bulbed tongues neatly over the pintles on the back of the rim lid thereby hingedly I connecting the lid to the body.

When the top die recedes the lid holder commences to move outwardly and raises the lid to a horizontal position. The'body is removed from the bottom die by the action of a curved ejectorarm simultaneously with the outward movement of the lid holder.

When the hinged lid and body are being moved along from the back of the third botton die bythe next oncoming body the lid passes over an inclined bracket which is adapted to keep the lid in its raised position. until it is passed within the sphere of operation of a closing device located at the discharge end of the press.

Now the present invention has been devised in order to provide extremely simple and e'flicient means for facihtating the-cor rect closing and discharging of hingedly connected lids and bodies fromthe machine. In" order thatthe invention may be readily understood reference will now be had to the accompanying sheets of explanatory draw- 1 ings, wherein Figure 1 is a view in perspective of a lid and a body blank of a receptacle.

Fig.2 is a'view' in perspective of a l1d and a body blank showing the-hinge mem bers. formed thereon by the first and second set of dies of the press.

Fig. 3 is a view in perspective showing the lid hingedly connected to the body of a receptacle and as removed from the third set of dies.

F-lg. 4 is aview in sectional elevation of part of the press show ng the closing device comprising the present invention applied thereto. Y

Fig.5 is a view in plan of part of the press showing the improvements applied thereto.

, Fig. 6 is a' view in sideelevation of the pressfitted with the closing device constructed in accordance/with the present in ventlon.

' In Figs. 4, 5 and 6 the press is shown in I faint lines and the improvements are shown in heavy lines.

' Figs. 7 and 8 are'views in side elevation of the closing device drawn to a larger scale than Figs, 4:, 5 and 6 and showing the parts thereof in their neutral and operative positions, respectively.

In the drawings like characters of reference have been employed to indicate slmilar parts in the different views and the numerals 1 and 2 designate the lid and body blanks,

respectively, of a receptacle. The hinge members of the 'lid comprise rolled pintles 3 and the hinge members of the body comprise bulbed tongues 4:. The hinge members 3 and 4 ofthe lid and body are constructed asshown in Fig. 2 and are hingedly connected'as shown in Fig 30f thedrawings.

The frame 5 of the press is fitted with three bottom dies 6 and a reciprocatingly mounted die head 7 carrying three top dies 8.: Theguideways 9 for the lids and bodies are located in the front and rear of the bottom diesand the push pads 10 are arranged to force the lids and bodies from the guideways on to the bottom dies. The lids and bodies are removed from the bottom dies and returned to the gu'idew 'ays by means of the ejector arms 11. Thelids 1 are placed on the 'third bottom die by a holder 12 and when a'hinged lid and body are passed along the guide-way toward the discharge end of the press the lid passesoveran inclined bracket 13 which is adapted to keep the said lid horizontal and clear the saidthird die and operative parts connected therewith.

Thehingedly connected lid and body after passing beyond the bracket 13 come within the sphere of operation of the closing depresent invention. ,7

The closing device comprises a bifurcated bracketlt which is bolted to the frame 5 in advance of the guideway 9 for the lids'and fitted with two flat springs 15. The springs 15 are disposed and curved in such a way that the freeedg'es .of the lids will fall and rest thereupon when a hingedly connected fitted to the spindle in the bifurcationof the bracket. The upper end of the arm 17 is formed into a jaw 18in which is pivoted the angle portion of a small bell-'crank19 having one arm projecting forwardly and the other arm projecting downwardly. The for-' wardly projecting arm of the bell-crank '19 is fitted with a spindle 20 carrying rollers 21 and the opposite arm of the bell-crank normally is kept thrust forwardly againsta stop'or abutment 22 by the' 'action of a spring 23. i

The spring 23 is carried on a pin 24' fitted to and projecting rearwardly from the arm.

17 vand a nut or nuts 25 are fitted to the pin to adjust the pressure of the spring on the depending arm of the bell-crank 19.

"The outer end of the spindle 16 is fitted vice which forms the subject-matter of'the with a forwardly projecting and downwardly" inclined arm 26 which is connected by: an

adjustable link or rod 27 to the upper end of a lever 28, the lower end of which is pivoted to a stud 29or the like 011 the side of the frame 5. v

v A roller30 is mounted on thefl'ever 28 about midway of its length and this roller is kept bearing against a cam 31 carried on a shaft 32 passing transversely through the rear of frame by a spring 33. One end of th'e spring 33 is connected to the lever 28 and the opposite end is connected to a stud 34 or the like on the side of the frame 5.

The guide-way '9 for the bodies extends beyond the third bottom die 6 in order to insure the bodies retaining their correct vertical positions while being directed to a discharge chute 35 fitted 'detachably to a bracket 36 fittedto the side of the frame, 5.

When a hingedly connected receptacle is pushed clear of the inclined bracket 13 and the lid falls upon the springs 15 the lever discharge chute.

28 is timed to move rearwardly thereby causing the arm 17 to move forwardly and downwardly. The forward and downward movement of the arm 17 causes the rollers 21 on the bell-crank 19 to bear with a resilient pressure on the top of the lid and press it gently toward the body.

The downward pressure of the rollers 21 on the lid causes the springs 15 to be pressed rearwardly from beneath the free edge of the lid thereby leaving the lid to close freely or to be pressed downwardly by the said rollers.

The closing device is operated during the period when a lid and a body are being connected on the third bottom die and the said device is returned to its normal position prior to the said lid and body being moved within its sphere of operation.

The closing mechanism above described can be easily adjusted and obviates the distortion of the lid and body or the hinge connection therebetween when the receptacles are passing from the third set of dies to the The discharge chute can be arranged horizontally or be inclined at any desired angle and delivers the hingedly connected lids and bodies to a point required. Fitted to one side of the discharge chute there may be a spring as 37see Figs. 5 and 6to insure the positive and complete closing of the lid over the body of the receptacle.
